Introduced the method to realize the communication between programmable controller and power station controller based on Modbus RTU protocol with RS-485 serial port.

This system is in the form of distributed control structure and consists of the stand alone general process control station, gas stove control station, oil pressure station, featuring excellent assembled and expansiveness.

On the basis of the factorial structure of the reliability of the manmachine interface s design about unmanned aerial vehicle s mission and control station,the system of evaluation index to estimate the reliability was established.

Control stations process directly carries out locale I/O data sampling, information alternation, control operation and logic control, completes real-time control in the whole industry process and rea.
